In a retrospective non-comparative study the objective surgical effect was calculated as the difference between the deviation at the day before surgery and the deviations 6 weeks and at least 1 year after surgery. Pre- and postoperative sensorimotor status and subjective outcome were evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In patients who underwent isolated inferior oblique muscle surgery the mean preoperative vertical deviation decreased from 15\u00b19 (distance)\/16\u00b110 (near) prism diopters (PD) (anteriorization) and 7\u00b15 (distance)\/9\u00b18 (near) PD (recession) to 4\u00b14 (distance)\/4\u00b16 (near) PD (anteriorization) and 2\u00b12 (distance)\/2\u00b13 (near) PD (recession) at the 1-year follow-up. In patients who underwent two-muscle surgery the mean vertical deviation decreased from 20\u00b111 (distance)\/21\u00b110 (near) PD preoperatively and 6\u00b17 (distance)\/6\u00b16 (near) PD at 1-year follow-up. Subjective assessment showed excellent scores among the patients treated with single-muscle surgery and slightly lower but also favorable scores among the patients treated with combined techniques. A direct comparison of the different outcome scores was not possible because of the more difficult initial situation in patients who underwent combined surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Isolated inferior oblique muscle weakening is an effective treatment option for superior oblique palsy up to 15 PD of vertical deviation in primary position.
